This issue was discovered in 6.2.x after testing LPS-52396. The issue is that now the MBMessage parent message references are being imported but they are not being exported. This issue is fixed in Master LPS-43841, however, not all of the logic is needed in 6.2.x so I am only backporting the part that is necessary.

Steps to reproduce

1. Have LPS-52396 implemented in 6.2.x
2. Prepare a Liferay cluster with two nodes.
3. Start node 1.
4. Accessing node 1, add a message board post with subject "node 1".
5. Start node 2.
6. Accessing node 2, add a message board post with subject "node 2".
7. Accessing node 1, reply to "node 2".
8. Export a LAR from the message boards portlet.
9. Create a new site "Blank".
10. Try to import the LAR into the message boards portlet of "Blank".
